Tar & Gravel Roofing
Ballasted Built Up Roofs / Tar and Gravel
Gravel removal (spudding) is required. We recommend installing at least 2” thick sprayed polyurethane foam on the roof to smooth out the dimples and create positive slope towards the drain. EnergyGuard® Acrylic Elastomeric Coating or EnergyGuard® Silicone Elastomeric Coating should be applied over the new foam to prevent UV degradation.
